이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
도 1 은 본 발명의 연료캡(12)이 연료주입 파이프(1)에 완전히 닫혀진 상태, 즉 걸림고리(5)의 걸림돌부(15)가 연료주입 파이프(1)의 외주면상에 돌출 형성되어 있는 록킹돌기(2)에 걸려서 연료캡(12)이 완전히 록킹된 상태를 도시한 것이다.1 is a state in which the fuel cap 12 of the present invention is completely closed to the fuel injection pipe 1, that is, the locking protrusion 15 of the locking ring 5 protrudes from the outer peripheral surface of the fuel injection pipe 1. The fuel cap 12 is completely locked due to the locking protrusion 2.
이러한 연료캡(12)을 열고자 할때에는 먼저 도 1 에서의 B방향, 즉, 커버(4)의 중앙부분을 손으로 눌러주면 스프링(8)에 의해 형성된 유격만큼 커버(4)가 하강하게되고, 이에의해 걸림고리(5)의 걸림돌부(15)가 점선도시된 부분과같이 록킹돌기(2)의 하측으로 이탈된다. When the fuel cap 12 is to be opened, the cover 4 is lowered by the clearance formed by the spring 8 by first pressing the direction B in FIG. 1, that is, by pressing the center portion of the cover 4 by hand. By this, the locking protrusion 15 of the locking ring 5 is separated to the lower side of the locking protrusion 2 as shown in the dotted line.
이때, 다시 커버(4)의 C부분을 강하게 눌러주게되면 그 외력에 의해 지렛대(9)의 작동단(11)이 일정각도 회전하면서 커버(4)가 젖혀지게되고, 걸림고리(5)가 록킹돌기(2)로부터 완전히 벗어나게되며, 이러한 상태에서 커버(4)를 손으로잡고 위로 올리면 연료캡(12)이 연료주입 파이프(1)의 개구면으로부터 이탈됨과 동시에 지렛대(9)가 힌지축(3)을 중심으로 일정각도 회전하면서 도 5 와같이 열려지게 되는 것이다.At this time, if the C portion of the cover 4 is strongly pressed again, the cover 4 is flipped while the operating end 11 of the lever 9 is rotated by an external force by the external force, and the locking ring 5 is locked. When the cover 4 is pulled up and raised in this state, the fuel cap 12 is released from the opening of the fuel injection pipe 1 and the lever 9 is hinged at the same time. Rotate a certain angle around the will be opened as shown in FIG.
상기와같이 연료캡(12)이 열린상태에서 주유건을 연료주입파이프(1)에 삽입하여 연료를 주입하게되면 연료캡(12)이 연료주입 파이프(1)의 개구면을 일정부분 막고 있게 되므로 오염물질의 침입을 방지할 수 있게된다.As the fuel cap 12 is opened as described above, when the fuel injection is inserted into the fuel injection pipe 1 and the fuel is injected, the fuel cap 12 blocks a part of the opening of the fuel injection pipe 1. It is possible to prevent the intrusion of contaminants.
한편, 연료캡을 닫아주고자 할 때에는 커버(4)를 잡고 연료주입 파이프(1) 측으로 눌러준다.On the other hand, when you want to close the fuel cap, hold the cover (4) and press the fuel injection pipe (1) side.
커버(4)를 전체적으로 눌러주게되면 도 4 에 도시된 바와같이 연료캡(12)이 먼저 연료주입 파이프(1)의 개구면에 밀착되고, 이후 걸림고리(5)가 회전하여 연료주입 파이프(1)의 상면 외측에 걸리면서 1단 닫힘상태가 된다.When pressing the cover 4 as a whole, as shown in FIG. 4, the fuel cap 12 is first brought into close contact with the opening of the fuel injection pipe 1, and then the catch ring 5 is rotated so that the fuel injection pipe 1 It is caught on the outer side of the upper surface and becomes the 1st stage closed state.
연료캡(12)의 1단 닫힘상태는 작은진동이나 충격에의해서는 연료캡(12)이 개방되지 않으나 큰 충격이나 진동에 의해서는 연료캡(12)이 열릴 수 있는 상태이다.The first stage closed state of the fuel cap 12 is a state in which the fuel cap 12 is not opened by a small vibration or shock, but the fuel cap 12 may be opened by a large shock or vibration.
즉, 작업자가 주유후 연료캡(12)을 닫지않더라도 차량 주행에 의한 진동과 연료캡(12)과 커버(4)를 구성하는 구조물의 자중에 의해 닫혀서 상기와같은 1단 닫힘상태가되어 연료증발가스의 외부 유출을 차단할 수 있도록 한 것이다.That is, even if the operator does not close the fuel cap 12 after refueling, the fuel cap 12 is closed due to vibration caused by driving of the vehicle and the weight of the structure constituting the fuel cap 12 and the cover 4, and the fuel cap 12 is closed as described above. It is designed to block the outflow of gas.
한편, 상기와같이 연료캡(12)이 1단 닫힘상태로 존재하는 상태에서 작업자가 커버(4)의 상측을 강하게 눌러주게되면 도 1 에 도시된 바와같이 걸림고리(5)의 걸림돌부(15)가 하강하여 록킹돌기(2)에 완전히 걸리게되므로서, 연료캡(12)이 연료주입 파이프(1)의 개구면을 차단하는 상태가 되며, 이러한 2단 닫힘상태에서는 걸림돌부(15)와 록킹돌기(2)의 결합력에 의해 연료캡(12)이 열리지 않게된다.On the other hand, when the operator pushes the upper side of the cover 4 in a state where the fuel cap 12 is in the first stage closed state as described above, as shown in FIG. ) Is lowered to completely lock the locking projection (2), the fuel cap 12 is in a state of blocking the opening of the fuel injection pipe (1), in this two-stage closed state locking projections (15) and locking The fuel cap 12 is not opened by the coupling force of the protrusion 2.
연료캡(12)이 1단 닫힘상태로 존재할때에는 연료탭(12)의 저면에 형성되어 있는 고무재질의 밀착부(14)가 연료주입파이프(1)와의 가조립 상태를 유지하면서 기밀을 유지하게되고, 연료캡(12)이 2단 닫힘상태로 존재할때에는 걸림고리(5)와 록킹돌기(2)의 결합력 및 스프링(8)의 탄성력에 의해서 기밀을 유지하게된다.When the fuel cap 12 is in the closed state of the first stage, the rubber contact portion 14 formed on the bottom surface of the fuel tab 12 maintains airtightness while maintaining a temporary assembly state with the fuel injection pipe 1. When the fuel cap 12 is in the closed state of the second stage, the airtightness is maintained by the coupling force of the locking ring 5 and the locking protrusion 2 and the elastic force of the spring 8.
상기 설명과같이 동작하는 본 발명에 의하면, 연료주입시 연료캡(12)이 연료주입 파이프(1)로부터 완전히 이탈되지 않음에 따라 연료캡(12)의 분실을 사전에 방지할 수 있으며, 연료주입시 오염물질의 연료탱크 내 침입을 사전에 차단하여 연료필터 및 인젝터의 막힘현상을 방지할 수 있는 것이다.According to the present invention operating as described above, since the fuel cap 12 is not completely separated from the fuel injection pipe 1 during fuel injection, it is possible to prevent the loss of the fuel cap 12 in advance, and fuel injection It is possible to prevent clogging of the fuel filter and injector by blocking the infiltration into the fuel tank in advance.
이상에서 설명한 바와같이 본 발명은 연료주입파이프를 개폐하는 연료캡을 이중열림방지구조로 형성함과 동시에 연료캡의 개방시 연료주입 파이프로부터 이탈되지 않도록 하므로서, 연료캡의 분실을 방지하고, 연료주입시 연료캡이 주유건이 삽입될 수 있는 정도로만 개방되므로 연료탱크 내로의 오염물질 유입을 차단하여 연료필터의 막힘 및 인젝터의 막힘현상을 방지할 수 있도록 한 연료캡구조를 제공하는 효과를 기대할 수 있다.As described above, the present invention forms a fuel cap that opens and closes the fuel injection pipe as a double opening prevention structure, and prevents the fuel cap from being lost while being opened from the fuel injection pipe when the fuel cap is opened. When the fuel cap is opened only to the point where the fuel gun can be inserted, it can be expected to provide a fuel cap structure that prevents the inflow of pollutants into the fuel tank and prevents the clogging of the fuel filter and the clogging of the injector.
